GGT6 gene expression is upregulated during AMK‐induced gastric cancer formation, which may provide favorable conditions for the proliferation and survival of gastric cancer cells, and GGT6, together with other genes, such as Mapk13, Nme1, Gsta4, etc., participates in the signaling and gene regulatory network during AMK‐induced gastric cancer formation. GGT6 may be used as a potential biomarker or a therapeutic target that provides new ideas for early diagnosis and treatment of gastric cancer) [68]. The gene discussed is GSTA4; the disease is gastric cancer.
